To all whom it may concern:

Be it known that I, Lno EHRLIen, a citizen of the United. States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Mail-Chutes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a fragmentary rear elevational view; Fig. 2 is a fragmentary side elevational view; Fig. 3 is a detail view illustrating the connection between the cable and the gate for opening and closing the letter-aperture; Fig. 4 is a horizontal sectional view on the line 4-4 of Fig. 2; Fig. la is a perspective view of part of the lever or latch controlling mechanism; Fig. lb is a detail view illustrating the connection between the door of the collecting box and the letter-aperture-gateoperating mechanism; Fig. 5 is a fragmentary side elevational view of the chute as viewed from the side opposite to that shown in Fig. 2; Fig. 5L is a sectional view on the line 55d of Fig. 10; Fig. 6 is a detail view of a part of the mechanism for locking the tube sections in position; Fig. 7 is a fragmentary front elevational view illustrating part of said locking mechanism; Fig. S is a detail view of a strip for holding the pane of glass in position; Fig. 9 is a horizontal sectional view on the line 9 4) of Fig. 5; Fig. 9a is a detail view of the bar-locking spring which is operated by the movable part of the tube section; Fig. 9b is a sectional view on line 9b-9b of Fig. 5; Fig. 10 is a front elevational view of the mail chute in position; Fig. 11 is a detail view of the rotary disk which cooperates with the letter-aperture gate; Fig. 12 is an elevational view as seen from the inside of the letter-aperture gate, showing the same in position; Figs. 13, 14, 15 and 16 show the gate in its diiierent positions; Fig. 17 is a detail view of the gate; Fig. 18 is a side elevational view as seen from the inside of a modified form of gateoperat g mechanism; Figs. 19, 20 and 21 are views illustrating the different modified forms of gate-operating mechanism; Fig. 22 is a detail view illustrating one form of discharging mechanism for the contents of the collecting box; and Fig. 23 illustrates another form of discharging mechanism for the collecting box.

This invention relates to a new and useful improvement in mail chutes for public buildings, the object being to construct a chute in such manner that the several sections composing the tube may be so manipulated as to give access to the interior of the tube.

Another object is to provide the apertures through which mail may be introduced into the chute from the different iloors, with suitable gates or closures which may be moved to their open or closed positions from the interior of the tube, and held in such position by means of a spring. These gates, in addition to being independently and manually operable, are collectively and mechanically operable by the door of the collecting box at the bottom of the chute, whereby when said door is opened all of the gates are moved to a closed position and in this manner letters and packages cannot be mailed while the collector is removing the mail from the box.

Another object of the invention is to provide the collecting box with a tilting section to facilitate the removal of mail therefrom.

Another object is to so construct the tube sections that they may be transported to the point of installation in dismantled condition, the parts being in readiness for assembling.

The parts of the tube sections may thus be nested and occupy a small space compared to the space occupied by the assembled tube sections.

Vith the above-mentioned principal objects in view, the invention consists in the construction, arrangement and combination of the several parts, all as will be hereinafter described and afterwards pointed out in the claims.

In the drawings, 1 indicates the vertical wall of a building and 2 the lloors thereof, these parts being illustrated conventionally for the purpose of locating the same with respect to my improved mail chute.

Referring to Fig. 9, the tube sections of my mail chute consist of a back plate 3 which is composed of pieces of sheet metal cut in appropriate lengths and connected together so as to extend practically throughout the length of the chute. rThis back plate may be hanged at both side ed es (only one flange 4, however, is shown in t.ie drawings), for the purpose of giving it strength. The back plate 3 is secured by suitable fastening devices to the vertical Wall of the building in such manner as to provide a space between said back plate and the vertical wall of the building, as shown in Fig. 2. This back plate 3 may also be connected to thimbles 5 (see Fig. 10), which thimbles are in the horizontal planes respectively of the floors of the building. 6 indicates facing plates secured to the back plates 3. rlhe joints between the back and facing plates may be broken so that the said plates constitute splices for each other. rlhese plates are riveted together at the building, the heads of the rivets being counter-sunk in the facing plate so as to offer no obstruction to the descent ofl mail. The facing plate 6 is as wide as the interior Width of the chute, its edges forming shoulders by which rabbeted joints may be made with the side walls of the tube sections. Each tube section consists, in addition to the facing plate 6, which forms the back wall of the tube, of two side angles 7 constituting the side Walls of the tube section and a front wall, which latter is made up principally of glass panels through which the condition of the interior of the tube may be seen. The angles 7 may be made up by forming a flange along one edge (the forward) of a sheet metal plate, as shown in Fig. 9. These angles are connected together at their upper and lower edges by means of connecting straps 8 riveted or otherwise fastened thereto. In addition to the straps 8, the angles have secured to them a plate 9 which contains the mail-receiving apertures and the frames 10 in which the glass panels are mounted. Frames 10 are preferably made of polished brass so as to give an ornamental finish to the tube sections. The panels of glass, indicated at 11, are arranged inside the frames 10 and are held in position by strips 12, the latter being preferably thin spring metal of suitable character and which are securedto the inner faces of the flanges or front legs of the side lates 7. As the glass panels 11 are not usua ly of uniform thickness, l prefer to cut the free edges of the strips 12 as shown in Fig. 8 so as to form independently yielding spring tongues. These tongues are placed under tension and in addition to holding the glass panels 11 tightly against their frames, leave no crevice in which mail may be caught.

Means for shedding the mail and preventing it from being caught by the upper ends of the strips 12, is illustrated in Fig. 8, Wherein it will be seen that the metal strip is beveled and bent so as to hug the inner face of the chute closely.

The length of the so-called tube section is coincident with the length of the side plates 7, and one of these side plates is hinged substantially throughout its length to the back plate 3, as shown in Fig. 9. The tube section composed of the front and two side walls may thus swing outwardly from the back wall, the said tube section clearing the floor and ceiling in its swinging movement.

'i he thiinbles 5 before referred to have their front and side walls tapering, as shown in Fig. 10. Each thimble is flush with the floor but projects a short distance below the ceiling so that vr hen the tube section is closed it embraces the tapered lower end of the thimble. ln this manner mail falling from above and passing through the thimble cannot be caught upon any projection at the joint between the upper end of the swinging tube section and the lower end of the thimble. rIhe lower end of each tube section may swing free of the thirnble located thereunder.

rihe means for locking the tube sections closed consists of a vertically slidable coupling sleeve 13 which is carried by a slide bar 14, said bar being guided in its movements by slot and pin connections to the flange 4 of the back plate. The coupling sleeve 13 is in the form of an open-ended box whose back wall is housed behind the thin cover plate 15 constitutin y a flush portion of the facing plate 6. 'lhe side and front walls of the sleeve 13 are of such size and shape as to snugly fit around the lower end of the swinging tube section, shown in Fig. 5a. The lower end of this coupling sleeve section is at all times rece'ved in the thimble 5. When the rod 14 is moved downwardly it carries with it the coupling sleeve section 13, which is telescopically housed in the thimble 5 when it releases the lower end of the swinging tube section, which may then be swung outwardly. VJhen the sleeve section 13 is closed and the rod 14 is raised the coupling sleeve section embraces the lower end of the tube section and loclrs the same in its closed position.

lt will be observed with relation to the construction just above described that no obstructions are left in the chute on which mail may lodge.

rlhe rod 14 preferably extends from floor to ceiling, as shown in TEig. 5, and is pivotally connected to an operating lever 16 whose rear end is provided with a curved slot for engagement with the pivot pin mounted in the back plate of the chute. The forward end of this lever 16 is provided with an operating handle 17, said lever also having an s both at its top and at its bottom.

lug on the plate 9. j lock 18 may be introduced through these l registering openings to loclr` the lever 16 in place.

The facing plate 6 has been heretofore described as being located between the edges of the side walls 7 so as to form a rabbeted joint. In order to insure a full closing movement being given the swinging tube section, means under control of said swinging tube section and actuated thereby are cooperatively related to the bar 14 and lool; said bar 1.4 in its lowered position, preventing any rising movement thereof until the swinging tube section is fully closed. By provision of this means no crevice is left at the back edges of the side walls 7 in which mail matter may be caught.

Referring now to Figs. 9 and 9", 19 indicates a leaf spring secured behind the back plate 3 and provided with a pin 2O which passes through an opening into said back plate in line with the back edge of one of the side walls 7 adjacent the bar 14. The back plate is provided with a slot in which the spring 19 may operate and engage a notch or recess 14u in the slide bar 14, which notch is in line with the free end of the spring when the bar 14 is in its lowermost position. In this manner when the swinging tube section is closed the spring 19 will be forced back out of the recess 14a; but when said swinging tube section is open, at which time the bar 14 stands in its lowermost position, said bar cannot be raised until the swinging tube section is closed and stands fully closed There are two springs 19 for each swinging tube section, one located near the top and the other Thus a key-operated! near the bottom thereof. The rear edge of bar 14 is cut and the tongue portion between the cuts is bent laterally as at 14b so as to col operate with lateral projections 7 L on the j side wall of the swinging tube section. When the bar 14 is depressed these tongues 14b are moved away from the projections 7. Vhen the swinging tube section is closed and the bar 14 raised the tongues 14b will move over and engage projections 7a and thus lock the sv. inging tube section home, as shown in Fig. 5.

Referring now to Figs. 11 to 18, the plate 9 in which is formed the mail-receiving apertures, has an offset which constitutes a housing for the gate 21, which gate is substantially in the form of an inverted L in cross-section. The short leg of the gate is designed to move across and close the mailreceiving opening or be housed in the housing out of the way of the mail. This gate has leaf springs 22 secured to its front face, the lower free edges of which springs engage a rod 23 constituting a pivot rod for the gate.

Rod 23 has a flattened face against which the gate is held by the springs 22 and one end of rod 23 extends outside the housing and is provided with a slotted crank 24 by which rod 23 may be rocked, and with it the gate 21 to its open and closed positions. 25 indicates a disk arranged in one end of the housing and having pins 26 which engage the gate, the inner edge of disk 25 being knurled so that it may be manually rotated. The normal position of the slotted roel: arm 24 is the raised one, as indicated by dotted lines in Fig. 13, in which position the gate uncovers the mail-receiving openings. Should this arm be depressed at the time mail is being introduced into the chute, as shown in Fig. 14, it will be obvious that the gate cannot close the opening. Under these circumstances the springs l2 yield and permit the flat faced pivot rod 23 torotate independently. The friction of the springs 22 is such lthat they will not force the gate to assume its normal position relative to rod 2,3 when once the gate is displaced, as in Fig. 14, and this is taken advantage of, as illustrated in Fig. 15, to enable the operator to manually move the gate to a closed position, notwithstanding the fact that the rock arm 24 is in its elevated position. In Fig. 16 I have shown the position of the parts when restored by the operator from the position to which they were moved in Fig. 15. This method of frictionally mounting the gate enables it to be manually positioned by the person having access to the interior of the chute as when the chute is opened after the operation of bar 14. Thus if the chute is out of order in the upper stories of a building the gates co operating with the mail-receiving apertures on the upper floors may be closed without disturbing the gates on the lower floors.

In Fig. 18 I have shown a modified form of gate in which the pivot rod 23 may be circular and held in a stationary position, the gate being frictionally mounted thereon so as to occupy either the open or closed position to which it may be moved.

In Figs. 19, 2O and 21 I havev shown another modification of manually operable means for opening and closing the gate, in which the gate is mounted by means of leaf springs on a flat-faced rock shaft '23 corresponding to the shaft shown in Figs. 12- to 17 inclusive. 25 indicates a rocking element having a projection 26 located in front of the gate. The sleeve 25 has a handle 27 at its front end by which it may be rocked, and when the parts are moved to the position shown in Fig. 1.9 the gate is closed. By raising the handle and depressing the projection 26 out of the way of the gate, the gate may be opened.

Means for mechanically operating all of the gates is shown in Figs. 1 to 4a inc usive. The chute discharges into a collecting box 2S and this box is provided with a hinged door 29 locked by a suitable pad lock to which the mail carrier has a key. The door 29 carries a pin 30 which cooperates with a recess in the forward end of a spring-pressed arm 31. This arm is connected by a rulejoint to a sliding member 32 which is slotted for the passage of a cross key 33, whereby said member may be moved longitudinally and prevented from turning. The bearing for the sliding member 32 is arranged within the box 28. A spring 34 is mounted on this bearing to hold the member 31 in normal aosition. The outer end of the sliding memer 32 is provided with a worm 35 which operates in a sprocket wheel 36. The bore of the sprocket wheel has threaded engagement with the worm 35. A yoke .piece 37 embraces the sprocket wheel and provides a bearing for the hollow axle thereof, said yoke piece permitting rotation of the sprocket wheel but preventing longitudinal movement thereof.

38 indicates a flexible band preferably made of steel and containing perforations for engagement With the teeth on the sprocket Wheel 36. This band passes under idle rollers 39 mounted behind the back plate 3. The ends of band 38 are connected to wires or cables 40 whose upper ends are connected to a fiexible band 4l similar to the band 38, and which band 4l passes over an idle sprocket wheel 42 mounted behind the back plate 3 at the upper end of the chute.

40a indicates a slotted block arranged upon the wire 40 and clamped thereon by a set screw 43. This block has an arm 44 with an open loop at its end which engages the eye of the rock arm 24 which is on the end of the flat-faced rod 23 on which a gate is mounted. The back plate 3 and facing plate 6 are cut away at appropriate points in order to permit of the positioning of the slotted blocks 40a. This opening is closed by a movable plate 3a, see Fig. l, which plate is held in position by suitable screws. There is a connection between cable 40 and each gate in the chute so that when said cable is operated by the opening of the door 29 all of the gates are closed. -When the door 29 is closed all of the gates will, in the normal position of the parts, be opened. In the event that a person is mailing a letter or letters at the time the door 29 is opened, the springs 22 will permit the arm 24 to 'be depressed by the cable 40, as shown in Fig. 14. No damage, however, will be done to the gate which is held open by reason of the letters in its path; nor will the fact that one gate is prevented from fully closing its opening interfere with the cable 40 or with any other gate. i/Vhen the door 29 is fully open as shown in Fig. 4b, the stud 30 is disengaged from the arm 31, such disengagement occurring shortly after the door 29 starts to swing, and before it reaches its fully open position. This insures a full stroke being imparted to the lever 3l at each opening and closing movement of the door 29. The stroke of the lever 3l and its connected sliding member 32 causes the worm 35 to move longitudinally in the sprocket 36, and the sprocket is thus made to rotate the proper part of a revolution to give to the cable 40 requisite movement to operate arms 24.

Should it be desired for any reason, such for instance as to make repairs, etc., to close all of the gates so as to prevent the introduction of mail into the chute, the door 29 may be opened by an authorized person who manually forces the pivoted member 31 and its connected parts rearwardly. In order to prevent reengagement between the door and the lever 31 after the door is closed, lever 3l could be moved against its spring 34 and introduced behind a shoulder 45 in a bracket 46 arranged inthe box 28. Should it be desired to disconnect the lever 3l from the door 29 so that the gates would remain open, even when the door 29 was open, lever 3l would be swung against the spring 34 and located behind the shoulder 47 in the bracket 46. This bracket and shoulder is illustrated in detail in Fig. 4a.

In Figs. 22 and 23 T have illustrated means for facilitating the discharge of mail from the collecting box 28. ln Fig. 22 there is shown a hinged plate 48 having flanges at its sides and when the door 29 is opened this hinged plate may be dropped so as to discharge the mail into the bag. In Fig. 23 a box 49 open at its top is arranged inside of the box 28 and hinged at its forward lower edge so that the entire contents of the mail in the collecting box may be lifted and dumped.

l am aware that minor changes in the construction, arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
